Is there a way to change monster height through a function ?

Thanks for the answer !!!!

how do i see what errors gzdoom builder is having when compiling zdoom ACS?

it says there is an error and there is a red exclamation next to "#include "zcommon.acs"" yet it seems to compile without a problem as the scripts end up working...super weird.

is there any way to see what the issue is? because right now its not showing any error.
i did have something popup asking if it could access a file though...but i cant seem to get it to come back. really weird.


im actually using Johnnyfives weather system (incredible) and haev never had issues. well now that im using GZDB when i go to compile it isnt a fan of compiling with the "#import "weather.acs"" underneath the include zcommon.acs.

the weather is in fact in the GZDB folder. not really sure waht teh issue could be.


EDIT

also for some reason GZDB wont allow me to compile the script
/////
script 15 open
{
PlaySound (39, "torture3",Chan_body, 1, true, 2.0, false);
}

why? do i need to update my zcommon.acs? if so where is the download...ive been looking FOREVER!
EDIT
if anyone is curious on how to update their zcommon.acs go to "https://zdoom.org/downloads"

updated my zcommon...and now it compules and no sound plays. seriously....why does nothing work all of a sudden?

Any way to use a textured 3d model as terrain?

Any way to use a textured 3d model as terrain?

It is possible. But keep in mind that collision for the model is calculated only as a box...
So I can imagine a textured 3d model of terrain used for scenery, or in places where player cannot enter. Otherwise, not.

[Clay]

Well I was thinking of going with the use of MODELDEF instead. From what I understand, 3d models do not have collision. If that is true, then could I use a 3d map and build 'real' geometry around it giving that illusion of being in a 3d level?

You can add small actor_box at/in/near surface of model, to make illusion that model have corresponding it size hitbox, it but this take much, much time.

but anytime i try to change ammo, it always prints "410 bore shells loaded" but the attack it's still the colt45 one, also it still uses the same ammo, how can i change this behaviour? since i know that the code has errors, but i can't understand which ones.

[Apeirogon]

How make enemy blind? More preciesely how make him walk and attack only at heared direction of sound? Purpose, make cacodemon, which have one BIG eye, with shootable eye.

[worldendDominator]

MetallicaSepultura, what exactly are you trying to do in 3rd line after 410Bore label? The one with A_JumpIfInventory. Amount 0 means that it will jump if you have max amount of specified inventory item.

[SHayden]

Quick question, how do i "bind" certain animation for certain type of attack. I'm doing something for myself but....
Let's put it this way, for example revenant has 2 attacks, melee and rocket. When it fires rocket we see his shoulder cannons firing rocket, and when he punches, we see him swinging his arm(logic, right?)
THIS is the problem I have, how do i separate "animations" for each attack I legit tried everything and I just can't bind 2 different animations to 2 different attacks(let's say i'm doing something similar to the example i just made)

Hope you guys understand what's the problem

[worldendDominator]

You give the revenant Melee and Missile states with different sprites.
Or in case of a custom monster, you give it several attack states (melee or missile, it doesn't matter) with different sprites.

[SHayden]

That doesn't help... I just said I tried everything but it gives me one of those animations for both attacks

[worldendDominator]

Let's say one animation uses sprites BLAH E, F and G, and other uses BLAH H, I, and J.
The respective states should be like this:

Code: Select all • Expand view

Attack1:
    BLAH E 7
    BLAH F 7
    BLAH G 7 A_CustomMissile("BlahMissile")
    Goto See
Attack2:
    BLAH H 8
    BLAH I 8
    BLAH J 8 A_CustomBulletAttack(10,5,3,4)
    Goto See


If you still don't understand, post the actor code here (preferably under a spoiler if it's long).

[SHayden]

I'm copying mod empathy since i'm fairly new to this so...mod is not mine...blah blah blah...

I know there are lot of mistakes in here so don't laugh i'm still learning i'm complete noob for decorate

[worldendDominator]

You should've mentioned you're talking about a playerpawn and not a monster. That changes everything.
If you want main fire and altfire make the pawn do different animations, you need to distinguish them somehow in the pawn's Missile state. It should be possible to do with a token (inventory item without any properties), but there may be other ways.
